Smartphones and other mobile devices, that are able to support up to 2 TB of expandable storage via microSD cards, are available since 2016. But the largest capacity we seen so far is only 400 GB. With the advancement of NAND flash technology, both Micron and SanDisk have unveiled their 1 TB microSD cards to the public.
The Micron c200 microSD card will be utilizing Micron’s own 96-layers 3D QLC NAND Flash in order to reach the targeted 1 TB capacity. The card will be able to reach read speed at 100 MB/s and write at 95 MB/s.
The SanDisk Extreme, Extreme PLUS and Extreme PRO microSD cards both get a 512 GB and 1 TB model into their lineup. Western Digital/SanDisk does not reveal which NAND technology is being used on the card. The SanDisk 1 TB microSD cards are able to read and write at 160 MB/s and 90 MB/s respectively. They do have an edge on the Micron c200 in read performance.
Micron says the c200 microSD card will start shipping in the 2nd quarter of 2019. The 1 TB SanDisk Extreme microSD card will be priced at $449.99 USD (MSRP), available in April 2019.
